Colocalization of KRAP with IP3Rs in the chief cells and the mucous cells of
the mouse stomach. (A) Fluorescent confocal images of the base region of gastric glands
for KRAP (red), IP3R3 (green), and the merged photo. Arrows indicate the
apical membranes of the chief cells. (B) Fluorescent confocal images of the pit region
of gastric glands for KRAP (red), IP3R3 (green), and the merged photo. Arrows
indicate the apical membranes of the mucous cells. (C) Fluorescent confocal images of
the base region of gastric glands for IP3R2 (red), IP3R3 (green),
and the merged photo. Asterisks and arrow indicate the parietal cells and the apical
membranes of the chief cells, respectively. (D) Fluorescent confocal images of the pit
region of gastric glands for IP3R2 (red), IP3R3 (green), and the
merged photo. Arrows indicate the apical membranes of the mucous cells. Blue,
4′,6-diamidino-2-phenylindole (DAPI) staining; scale bar, 25
μm.
